We divide 74378321 by 539
We want to figure out the number of times 74378321 can be divided by 539.

Let's proceed to step 1:
If we divide 7 by 539, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 539

Step 2:
When dividing 74 by 539, we get 0 with a remainder of 74.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 74 to get 74.
Append the next digit (3) from the dividend to 74 and continue with: 743 / 539

Moving on to step 3:
When dividing 743 by 539, we get 1 with a remainder of 204.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 539 from 743 and we're left with 204.
Bring next digit (7) of the dividend behind the 204 and repeat the process: 2047 / 539

Step 4:
539 can be fit into 2047 3 times, resulting in a remainder of 430.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
The remainder is 430 after subtracting 1617 from 2047.
Take the next digit (8) from the dividend and append it to 430, then repeat: 4308 / 539

Going ahead to step 5:
539 goes into 4308 7 times with a remainder of 535.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 535 after subtracting 3773 from 4308.
Append the next digit (3) from the dividend to 535 and continue with: 5353 / 539

Let's proceed to step 6:
539 goes into 5353 9 times with a remainder of 502.
Record the quotient 9 as the next digit in the result. 
Result so far: 1379.0
Deduct 4851 from 5353 and we're left with 502.
Fetch the next digit (2) from the dividend, attach it to 502 and continue: 5022 / 539

Going ahead to step 7:
When dividing 5022 by 539, we get 9 with a remainder of 171.
Use 9 as the next digit of our solution. 
Result so far: 13799.0
If we take 4851 away from 5022, we end up with 171.
Bring next digit (1) of the dividend behind the 171 and repeat the process: 1711 / 539

Moving on to step 8:
539 can be fit into 1711 3 times, resulting in a remainder of 94.
The next digit of our result is 3. 
Result so far: 137993.0
If we take 1617 away from 1711, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 9:
If we divide 940 by 539, we get 1 and a remainder of 401.
Use 1 as the next digit of our solution. 
Result so far: 137993.1
Subtracting 539 from 940 leaves us with 401.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4010, and continue the process.

Step 10:
4010 divided by 539 is 7 with a remainder of 237.
Record the quotient 7 as the next digit in the result. 
Result so far: 137993.17
If we subtract 3773 from 4010, we get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Going ahead to step 11:
2370 divided by 539 is 4 with a remainder of 214.
The number 4 becomes the next digit in our result. 
Result so far: 137993.174
If we subtract 2156 from 2370, we get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 12:
539 goes into 2140 3 times with a remainder of 523.
Write down 3 as next digit of the result. 
Result so far: 137993.1743
The remainder is 523 after subtracting 1617 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5230, and continue the process.

Step 13:
539 goes into 5230 9 times with a remainder of 379.
The next digit of our result is 9. 
Result so far: 137993.17439
If we take 4851 away from 5230, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Let's proceed to step 14:
The number 539 fits into 3790 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 137993.174397
Subtract 3773 from 3790 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 15:
If we divide 170 by 539, we get 0 and a remainder of 170.
Use 0 as the next digit of our solution. 
Result so far: 137993.174397
Subtracting 0 from 170 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 16:
When dividing 1700 by 539, we get 3 with a remainder of 83.
Record the quotient 3 as the next digit in the result. 
Result so far: 137993.17439703
If we subtract 1617 from 1700, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

The final outcome is 137993.17439703, with a leftover of 8.3e-08.
